Nicely done video showcasing six species, narrated by scientists from the Cornell Laboratory of Ornithology. In order of appearance: Common Loon, Barred Owl, Common Nighthawk, White-rumped Sandpiper (very cool vocalizations), Northern Cardinal, and Magnificent Frigatebird.
Like it? Let Cornell University know by clicking the video over to their YouTube page, and clicking on the "Like" button! IMO, videos like this beat the pants off of some of the other videos on their channel.
